Abstract: Methods and apparatuses for sidelink (SL) resource allocation in unlicensed spectrum in a wireless communication system. A method of operating a user equipment (UE) includes performing sensing on a SL interface; determining, based on the sensing, a set of available SL resources within a SL resource pool; and selecting a slot within the SL resource pool. The method further includes performing a listen-before-talk (LBT) channel access procedure before the slot; determining a presence of available SL resources from the set of available SL resources within the slot; and transmitting, based on the LBT channel access procedure being successful and the presence being determined, in an available SL resource from the available SL resources within the slot.

Abstract: Configuring control information comprises determining a frequency offset including an RB and RE level frequency offset, where the frequency offset is determined based on a lowest RE of an SS/PBCH block and a lowest RE of CORESET for RMSI, jointly configuring, using a first field of 4 bits, the RB level frequency offset with a multiplexing pattern of the SS/PBCH block and the CORESET, a BW of the CORESET, and a number of symbols for the CORESET for a combination of a SCS of the SS/PBCH block and a SCS of the CORESET, configuring using a second field of the 4 bits generating an MIB including the RB level frequency offset and the RE level frequency offset; and transmitting, to a UE, the MIB over a PBCH.

Abstract: A method and apparatus of a user equipment (UE) in a wireless communication system are provided. A method of operating a UE includes receiving a set of configurations; determining, based on the set of configurations, a number NperiodS-SSB of sidelink synchronization signals and physical sidelink broadcast channel (S-SS/PSBCH) blocks to transmit in a period; and determining, based on the set of configurations, a transmission window for transmitting the S-SS/PSBCH blocks in the period. The method further includes determining a set of candidate slots for transmitting the S-SS/PSBCH blocks in the transmission window; performing channel access procedures before the set of candidate slots for transmitting the S-SS/PSBCH blocks in the transmission window; and transmitting, to another UE, the S-SS/PSBCH blocks over a sidelink channel with shared channel access, upon successfully performing the channel access procedures.

Abstract: A UE in a wireless communication system is provided. The UE comprises a transceiver configured to receive, from a BS, a SS/PBCH block including the PBCH using a first frequency location (GSCN-Current) over downlink channels, GSCN-Current being based on a set of predefined synchronization rasters that is determined by a global synchronization channel number (GSCN). The UE further comprises a processor operably connected to the transceiver, the processor configured to determine the SS/PBCH block, identify content of a PBCH included in the determined SS/PBCH block, determine a configuration for at least one of the SS/PBCH block that is associated with a PDCCH including scheduling information for RMSI on the GSCN-Current or the SS/PBCH block that is not associated with the PDCCH including the scheduling information for the RMSI on the GSCN-Current.

Abstract: Methods and apparatuses for a repeated pattern over multiple slots in a wireless communication system. A method of operating a user equipment includes receiving a configuration for search space sets, determining a combination (X, Y), and determining a bitmap for a search space set from the search space sets based on the configuration. Each bit in the bitmap is associated with a slot within a group of X consecutive slots. A physical downlink control channel (PDCCH) reception occasion in a slot is present if the associated bit for the slot in the bitmap has a value of “1” and is absent if the associated bit for the slot in the bitmap has a value of “0”. Bits with a value of “1” are consecutive in the bitmap. The method further includes receiving PDCCHs in PDCCH reception occasions that are indicated as present according to the bitmap.

Abstract: A method of a base station (BS) for transmitting synchronization signals in a wireless communication system. The method comprises generating a primary synchronization signal (PSS) including one of multiple PSS sequences that is generated based on a M-sequence of length 127 in a frequency domain, wherein the PSS indicates part of cell identification (ID) information using a cyclic shift performed on the M-sequence generating the PSS; generating a secondary synchronization signal (SSS) including one of multiple SSS sequences that is generated based on multiple BPSK modulated M-sequences of length 127 in the frequency domain, wherein the SSS indicates the cell ID information using cyclic shifts performed on the M-sequences generating the SSS; and transmitting, to a user equipment (UE), the PSS and SSS over downlink channels.
